2 Claims.

This is a divisional application from the original application forBuilding construction led by applicant on December 14, 1936 under SerialNumber 115,701.

My invention relates to building construction and particularly to apressure relieving and wall strengthening joint.

Among the objects of my invention is to provide a pressure relieving andwall strengthening joint having a unitary structure thereby eliminatingthe necessity of fillers; to create a joint formed of a single sheet ofmaterial, and having a plurality of integral raised portions adapted tobe forced down by excessive weight to relieve pressure; to supply ajoint adapted to be folded on itself to produce a watertight course, andsuch other objects, advantages and capabilities as will later more fullyappear and which are inherently possessed by my invention.

While I have shown in the accompanying drawing a preferred embodiment ofmy invention, yet I wish it understood that the same is susceptible ofmodification and change Without departing from the spirit of myinvention.

Referring to the drawing, Fig. l is a plan view of my compressiblefiller before it is bent for use; Fig. 2 is an enlarged sectional viewfolded in use in building construction; Fig. 3 is a perspective view ofmy compressible filler partly unfolded.

My compressible filler comprises a body member Il having a centralportion 29 having integral therewith a plurality of spaced raisedportions 20, On either side of said central portion 29 and integraltherewith, is a level portion 28. Said body member I1 is adapted to bebent back on itself at both places indicated at 32, the meeting placesof the central with the level portion on either side thereof, so thatthe level portions 28 substantially meet to substantially cover saidcentral portion 29. When said level portions 28 are superimposed oversaid central portion 29, said level portions 28 contact said raisedportions 20.

It is Within the contemplation of my invention that the structure may bereversed, so that the raised portions may be integral with the upperportions 28 instead of the central portion 29 which would in that casebe level.

While I prefer to construct my joint or filler of ductile metal such aslead, or fiber, rubber or the like, yet it is Within the spirit of myinvention to construct my joint of any compressible material havingsubstantially the same qualities as lead. My invention providing for ajoint of one piece of material eliminates the necessity of expensivellers. By eliminating the need of any ller andmaking my joint of oneintegral part, I substantially decrease the cost and amount of materialand labor.

While I have shown as illustrated in the drawing raised portions incircular form, yet I wish it understood that my raised portions may bein the shape of squares, triangles, rectangles, bumps or any other formof raised portions without departing from the spirit of my invention.

My joint may be used in any type of building construction andparticularly where the construction is divided into zones. My joint maybe placed in any place and as many times as desired within each zone andat any place between units of a wall.

The raised portions are of any desired height, generally of sufficientthickness to create a joint of equal thickness to the mortar joint. Onepurpose of the fold is to produce a water-tight course. My joint comesin any desired width, and is delivered on the job cut to i'lt the proleof each individual pier, thereby eliminating any additional expense insetting. My joint is of sufflcient strength to carry the normal weightex- 25 pected to occur on the facing units.

In all buildings of stone, terra cotta, granite or marble faades certaindestructive movements occur which cause the facing blocks to crack orspall. These movements include the compression of steel, the expansionof stone due to temperature change, wind-stress, settlement, andvibration. `These conditions are frequently aggravated by faultysetting. To overcome any disastrous results from the above movements myjoint has been developed to incorporate a feature of elasticity into thewall which may not be obtained as well in any other manner. When theexcessive weight is placed on the facing blocks there is relief providedsimply by the raised portions of my joint being forced down, Whichautomatically restores the desired, intended Weight to the facingmaterial. With the use of my joint the building is zoned into storyheights. Where the stones are bondedon to the floor or in the use ofshelf angles, this material permits these types of construction tofunction as intended by assuring, for the life of the building, that theweight of the faade will rest on either the angle iro-n or the floor.Another desirable feature of my invention is the elimination ofsubstantially all future tuckpointing.

My invention herein is new and differs from my (so-pending applicationon a patent for Building construction, Serial Number 91,520, led July20, 1936, in that I have now provided that the raised portions on myjoint are formed in only one of the upper or lower portions, whereas inmy said previous application the raised portions occurred in both theupper and lower layers. With my new construction I eliminate the raisedportions on either the upper or lower layers thereby saving considerablein expense, material and workmanship as well as saving the necessity ofconstructing the raised portions on both the upper and lower layers sothat they may nest or meet. I also provide that the upper or lower layermay be in a pair of iiaps instead of a centrally bent portion.

Having thus described my invention, I claim:

1. A unitary compressible ller for use as a pressure relieving joint ina wall structure coniprising a sheet of metal having a central portionwith a plurality of spaced raised portions, and a level extension oneither side of said central portion, said sheet adapted to be bentinwardly upon itself so that said level extensions substantially meet toform an upper layer substantially covering said central portion andcontacting the raised portions of said central portion.

2. A unitary coinpressible filler for use as a pressure relieving jointin a wall structure comprising a sheet of metal having a central portionand a lateral extending portion on either side thereof, said sheetadapted to be bent back on itself so that the central portion forms onelayer and the lateral portions form another layer, one of said layerspositioned above the other layer, `and one of said layers being level,and the other of said layers having a plurality of spaced raisedportions, so that the level layer contacts the raised portions on theother layer.
